    There is power to be made with the shorter bell style 200 tuners.put on 150's

    BUT the heads will yield the biggest bang for the three mods your doing..

    Bigger jets on the mains may be safer but sometimes not needed . You just gotta put them on and do some plug checks ...You'll be amazed how much torque they will make...
